111 W. Wacker (formally Waterview Tower) is a skyscraper under construction in downtown Chicago, Illinois, United States. The original plan called for it to be 1,047 ft (319 m) tall.

In May 2008, construction ceased after the parking garage portion and most of the hotel floors were completed. The project was idle until in May 2010, a consortium of creditors and lienholders (called Clark Wacker LLC) took over ownership of the project and formed a Joint Venture with Related Midwest in July 2011 to restart and complete the project.

In 2012, 111 West Wacker Partners LLC, the new Joint Venture, proposed a completely new design that will repurpose the existing structure into a luxury, rental tower to better suit the current real estate market. As a result, the building will no longer contain a hotel and condominiums, but contain 506 rental units, an expansive first floor retail space and 439 parking spaces. The new building, designed by Handel Architects will be substantially smaller in height at 59 stories and 630 ft (190 m) tall.

Waterview Tower was originally planned to have parking for guests and residents on floors 2 to 11. A setback at the 29th floor level would have held a rooftop garden[1] in addition to being the amenities level for all building guests and residents. [2] The remaining 30th through 88th floors were to have comprised 233 condominium and penthouse residences. The tower was originally designed to be a concrete building with an exterior wall made of glass, granite and aluminum to generate a prismatic look. Per one of the city's approval conditions to include an outdoor garden, a terrace was planned to have spread over approximately 8,000 sq ft (740 m2) featuring landscaping, water elements, sun deck, and pet recreation area on the 29th floor.
